.NoN REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Dec. 16, 1919.

Application filed October 18, 1918. serial No. 258,670.

To all whom/it may concern:

Be it known that I, THO'MAS MARTIN, a subject of the King of Great Britian, and residing at 63 Riddiford street, vNewtown, \Vellington, in the Dominion of New Zealand, have invented new and useful Improvements in and Relating to Non-Refillable Bottles, of which the following is a specification.

This invention relates to bottles adapted to contain s irits or other beverages or liquids, its ObJBCt being to provide a simple and effective construction, which will be non-refillable, that is to say, a construction which after the initial filling, will permit of the contents being poured out, but will resist all attempts at refilling.

In carrying this object into effect, the in vention consists briefly of the provision within the neck of the bottle of an intercepting valve, controlled by means of a pendent weight, the novel and peculiaroperation of which serves to maintain the valves securely closed when the bottle is placed in any but the inverted position. Suitable bafliing or obscuring means are provided to render the valve inaccessible from the orifice of the neck order to prevent tampering.

In order that the nature of the invention and its construction may be fully understood, reference will now be made to the accompanying sheet of drawings, in which Figure l is a sectional elevation of a bottle constructed in accordance with the present invention.

Fig. 2 is asimilar view showing the upper portion and neck of the bottle in the inverted position.

Fig. 3 is a similar view showing the upper portion and neck of the bottle in an inclined position.

Fig. 4 is a sectional view of the upper portion of the neck of the bottle, illustrating by way of example, the alternative method of obscuring the valve.

The construction comprises a bottle 1 oi: any suitable shape in the neck 2 of which is provided a valve seating 3 preferably of rubber or other resilient material. For convenience in manufacture and to permit of the initial filling, the upper portion of the neck 2 above the seating 3 instead of being integral with the bottle, preferably consists of a separate piece adapted to be placed in po sition, and suitably secured as by means of a metal capsule or ferrule 4 embracing the neck.

Arranged above the seating 3 and adapted to co-ac-t therewith, is a valve 5, preferably of hemispherical or conical form and having 1ts upper side hollow or cupped as here shown. The valve may consist of porcelain, glass, or other rigid material, or if so des1red, the seating 3 may be of such rigid material, in which case, the valve itself may be constructed of rubber or the like.

Connected with the underside of the valve 5, by means of a flexible joint 6, is a weight 7, which depends downward within the bottle 1. The weight 7 is provided at or near 1ts upper end with a flange or series of projections 8, the arrangement being such that when the bottle is standing in the upright position (Fig. 1), the weight 7 will hang plumb and will hold the valve firmly down upon the seating 3 while the flanges or projections 8 will be clear of and at a slight interval below the underside of such seating.

Upon the bottle being inverted (Fig. 2), the flanges or projections 8 will rest upon the underside of the seating 3, thus sup porting the weight 7v and permitting the valve 5 to become unseated and so allow of the contents being poured out.

Should the bottle be inclined at any appreciable angle from the truly inverted position (Fig. 3), the weight 7 will be tilted to one side, thus causing the flange or projections 8 on one side only to engage the seating and so form a fulcrum for the weight, which then operates as a lever, in closing the valve.

It will be understood, therefore, that communication between the body of the bottle and the mouth or orifice of the neck can only exist when the bottle is in a truly inverted position, and in which position the introduction of liquid into the bottle from the orifice of the neck, if not scientifically impossible, is certainly impracticable as a commerical operation.

To prevent tampering with the valve, as by the introduction of a wire between the valve and its seat, in the upper portion of the neck between the orifice and the valve seat 3, are provided suitable obscuring means.

Thus, as shown in Figs. 1, 2, 3, this purpose is eft'ected by the employment of a baflle plate 9 of somewhat greater diameter than the valve 5, and arranged loosely within the neck. The same purpose may, however, be served in several different ways, as for example, as shown in Fig. 4 by forming a tortuous passage in the portion of the neck immediately beneath the orifice.

To prevent air-locking of the bottle when pouring out, a suitable hole or vent 10 is formed through the upper portion of the neck, such hole being preferably formed in an upward direction so that a wire inserted therethrough will approach the orifice of the neck rather than the valve.

I claim The combination with a bottle having a restricted outlet and a valve seat within the neck of the bottle and spaced from said outlet, of a cup-shaped valve above the valve seat and having a stem extending through said seat, a Weight below the valve seat and pivotally connected to the valve stem, a series of spaced projections formed on the upper end of said weight and adapted to engage the valve seat, and a baffle plate between the restricted outlet and the valve seat and having a knob portion adapted to seat within the valve.

In testimony whereof I have signed my name to this specification.
